Description of BS EN 62471-5:2015 2015This part of IECÂ 62471 provides requirements regarding photobiological safety of the optical radiation emitted by image projectors. This part of IECÂ 62471 does not deal with other hazards such as electrical, mechanical or fire hazards. This part of IECÂ 62471 provides requirements regarding:
The scope of this part of IEC 62471 is photobiological safety of image projectors including the emissions from laser-illuminated projectors that fulfill the requirements as specified in IEC 60825‑1:2014, 4.4 and for which visible light emission has been excluded from classification in IEC 60825‑1 . This part of IEC 62471 does not address safety requirements for laser display products where collimated laser beams — generally scanned — are employed. It does address those laser-illuminated projectors that employ a laser source to illuminate, for example, a micro-electromechanical system (MEMS) without scanned beams or crystal-based display projector system. NOTE Image projectors containing lasers are subject to those provisions of IEC 60825‑1 applicable to the embedded laser. See IEC 60825‑1:2014, 4.4 for which visible light emission has been excluded from the laser product classification. This part of IEC 62471 includes projectors for only visible image projection and does not include ultraviolet (UV) projectors, infrared (IR) projectors, general lighting service (GLS) lamps (GLS; defined in IEC 62471 ) or projector lamp systems used for general lighting, which are treated in separate International Standards.
